range hood

Abstract

The invention discloses a range hood. The range hood comprises an electrostatic device (1) and a cleaning device (2), and the cleaning device comprises a rotary spray head mechanism (21) which can spray cleaning medium fluid to the electrostatic device so as to clean the electrostatic device. According to the range hood provided with the electrostatic device, the cleaning device provided with the rotary spray head mechanism is arranged, the rotary spray head mechanism can spray the cleaning medium fluid to the electrostatic device, oil stains accumulated for years in the electrostatic device are scoured and removed through the rotary spray head mechanism, accordingly, the purpose of effectively removing the oil stains accumulated in the electrostatic device is achieved, and the filtering and separating effects of the electrostatic device on the oil stains in cooking fumes are further improved.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a range hood. Background technique [0002] At present, electrostatic separation technology is widely used in range hoods for the separation of kitchen oil due to its good oil separation effect and simple implementation method. Conventionally, range hoods that carry out electrostatic separation and adsorption of oil fumes often have electrostatic ionization modules and electrostatic collection modules, wherein the electrostatic ionization module is used to charge the oil particles passing through the module, and the electrostatic collection module is used to charge the Grease particles accumulate at the plates. [0003] After the range hood is used for a long time, the oil in the fume will accumulate and solidify in a large amount in the electrostatic device, especially the electrode plates in the electrostatic ionization module and the electrostatic collection mo...

AI Technical Summary

Problems solved by technology

[0003] After the range hood is used for a long time, the oil in the fume will accumulate and solidify in a large amount in the electrostatic device, especially the electrode plates in the electrostatic ionization module and the electrostatic collection module, which will affect the negative ion release of the electrostatic ionization module and the electrode plates in the electrostatic collection module The electric field strength between them affects the charging effect of the oily particles passing through the electrostatic ionization module and the separation effect of the charged oily particles passing through the electrostatic collection module, thereby reducing the filtering and separating effect of the range hood on the oily dirt in the fume

[0004] When the electrostatic device in the range hood needs to be cleaned, the conventional method currently on the market is to remove the entire electrostatic device from the range hood, and then put it into the range hood after the electrostatic device is cleaned. The cleaning method is more cumbersome

Another cleaning method that does not require disassembly and assembly of the electrostatic device has appeared on the market, that is, a heating wire is installed on the pole plate of the electrostatic collection module, so that the solidified oil on the pole plate is liquefied by heat and drips from the pole plate. If the heating wire is installed on the pole plate, the surface of the pole plate will not be smooth, so that oil stains are easy to accumulate at the connection between the heating wire and the pole plate and are not easy to fall off
